RV, Trailer, and Camper Electrical Connector Made Easy!

7 Pin Trailer Connector

Pro Plug

Easy to Wire and Install

The mounting requirements for the towing vehicle plug have changed very little over time, not keeping up with new applications. Currently, either drill a big hole in the vehicle for the plug to mount into or hang it from a bracket that has the big hole in it, often placing the plug in a vulnerable location. Both of these options require considerable depth behind the mounting plane for the connector housing to protrude and for the routing of the wiring into the connector housing.

Pro Plug, an easy to wire, easy to install, self-testing, surface mount 7 way RV  electrical connector that makes it possible to install a trailer connection where it couldn’t before.

7-Way to 7-Way Coiled Cord

A must have when connecting and using your trailer in the winter, especially in northern climates where ice, snow, and road de-icer chemicals are tough on trailer cord connector ends. When the trailer is not in use, remove the cord and store inside out of the weather. This heavy duty coiled cord has high quality 7-way blade style connectors on both ends, a tough protective jacket that retains it’s coiled shape, and it extends to 5 feet in length.
